Fruit Peel Soil Supplementation Induces Physiological and Biochemical Tolerance in Schefflera arboricola L. Grown Under Heat Conditions

Abstract Schefflera plant is propagated and grown under greenhouse cultivation, most of these greenhouses are low-cost. In the summer, heat generated in becomes a limiting factor for growth and, subsequently, limits production high-quality species conditions. The powder banana (B), orange (O), pomegranate (P) peels their combinations were added as soil supplementation at rates 8 16 g/pot to pots plants, which during summer season low-cost greenhouse. analysis was estimated after 150 180 days from planting. Heat conditions significantly inhibited relative rate, crop absolute rate (AGR) but fruit peel applications shown markedly mitigate its negative impact. Fruit augmented shoot root leaf pigments, decreased AGR reduction, promoted water content, increased membrane stability index (MSI), alternated phenotypic plasticity (PPI). total phenol flavonoid levels well antioxidant activity (DPPH), positively alleviated oxidative damage (decreased H 2 O MDA contents) that occurred leaves, induced heat-shock protein synthesis, leading plants with greater tolerance. Orange application potting more beneficial initiation development early phases life, effective increasing aerial portions inducing resistance polyethylene greenhouses.
